How to identify green onions, onions, leek seeds
The skin color of the three onions, onion, and leeks are all black and their shapes are similar. If you don't look closely, it's hard to tell, but when you look closely, there are still differences between the three. Onion seeds are shield-like, angular, slightly flat, with few and neat skin wrinkles, and a shallow umbilicus. The seeds of the onion were shield-like and the skin was slightly irregular and wrinkled. The umbilicus was very deep. The leek seeds are shield-like, and the skin wrinkles are numerous and fine, and the umbilicus has no obvious concavity. Moreover, in general, the weight of a thousand seeds of scallion stalks is between 2.8 and 2.9 grams, the weight of a thousand seeds of onion seeds is about 4.6 grams, and the weight of amaranth seeds is between 4 and 4.15 grams. Onion seeds are lighter and onion seeds are heavier. Thirdly, the seed coats of these three vegetable seeds are poor in water permeability, water swelling is slow, soaking is required before sowing, and the lifespan of these three kinds of vegetable seeds is short. Do not use seeds when planting seeds. Chip Wristband,Rfid Tag Wristband,Rfid Nfc Wristband,Disposable Rfid Wristbands Guangdong Xinye RFID Label Application Co., Ltd , https://www.xinyerfid.com
